Constructor Detail

ListsBackedMap

public ListsBackedMap(List<K> keys,
                      List<V> valueList)

Constructs a new ListsBackedMap.

Parameters:

keys - keys of the map

valueList - values of the map

Throws:

NullPointerException - if any of the specified objects is null

ListsBackedMap

public ListsBackedMap(List<K> keys)

Constructs a new ListsBackedMap.

Parameters:

keys - keys of the map

Throws:

NullPointerException - if any of the specified objects is null

Method Detail

containsValue in interface Map<K,V>

Overrides:

containsValue in class AbstractMap<K,V>

get

public V get(Object key)

Specified by:

get in interface Map<K,V>

Overrides:

get in class AbstractMap<K,V>

put

public V put(K key,
             V value)

Specified by:

put in interface Map<K,V>

Overrides:

put in class AbstractMap<K,V>

remove

public V remove(Object key)

Specified by:

remove in interface Map<K,V>

clear in interface Map<K,V>

Overrides:

clear in class AbstractMap<K,V>

getEntrySetIterator

protected Iterator<Map.Entry<K,V>> getEntrySetIterator()

Description copied from class: AbstractMapWithSet

Returns the iterator of the entry set.

Specified by:

getEntrySetIterator in class AbstractMapWithSet<K,V>

Returns:

the iterator of the entry set.
